CHAND'ELIER.

SPECIFICATION formingpart of Letters Patent No. 245,894, dated August 16, 1881.

Application led March 3l, 1881. (Model.)

To all whom 'it may concern:

Beit known that I, SAMUEL B. H. VANGE, of New vYork city, New York, have invented certain new and useful Improvements in Chandeliers, of which the following is a specification.

My invention relates to drop-light chandeliers having fixed branching arms supporting stationary lights and a center slide or droptube supporting atdrop-light.

The object ot' my invention is to improve the construction of the central stem or tubes ofthe chandelier which contain the gas-ducts supplying the tixed branches and the droptube, so that the gas will not only be supplied to the said parts by distinct and independent channels, but which will enable the several concentric tubes or sections of the stem to be put together and finished in a manner more convenient and si mple than hitherto, and which will also serve to prevent the exposure of the exterior of the drop-tube to gas-scented spaces or surfaces in the stem, as hereinafter fully set forth.

In the annexed drawings, Figure 1 presents a vertical section ot' such partsof a drop-light chandelier as embody my invention, the same being, ot' course, much shortened for illustration. Fig. 2 is a cross-section on :1: x, and Fig.A 3 a plan of the top coupling.

The central stem ot the chandelier is surmounted, as usual, by a coupling, a., which screws at the top to the gas-nipple projecting from the ceiling', or to a pipe extending therefrom, as will be understood. In a central opening in this'coupling is screwed a slender ceiltral gas-tube, b, which extends downward through the center of the chandelier-stem, and terminates atashort distance below the branching arms, as shown. c indicates the drop-tube, which slides telescopically over the gas-tube b, having a suitable form of stufng-box, d, at its upper end to embrace the tube b gas-tight,

while its lower extremity supports the drop-V preferably square in cross-section, as seen in Fig. 2, and slides through a square opening of snug t in an ornamental cup, f, screwed onto the end of the inclosing-tube o, as seen in Fig. l.

In one former chandelier ot' this class the drop-tube moves gas-tight in its inclosiug-tube in the manner of a piston, and the central gastube, b, is not used, while around the inclosing-tube has been placed a second tube of larger size, leaving an annular space between the two, through which the gas is supplied to the iixed arms. In my chandelier, however, it will be seen that the drop-tube moves gastight on the center gas-tube, b, and moves loosely in the tube c, which simplyincloscs it. As this arrangement of tubes, however, has also been used before, it forms no claim of mine. It will be seen, however, that in my construction the space between the drop-tube and its inclosing-tube c forms a free air-space, and a slot, g, extends through the top ofthe nipple into this annular air-space to admit the metallic ribbon h, which extends from asprin drum (not shown) fixed on the head ot' the chandelier, and connects to the top ot` the droptube in a manner now employed in chandeliers, so as to suspend or balance the droptube and its attachments at any position, as will be readily understood. This slot or passage g thus renders the space in which the drop-tube moves open to the atmosphere at the top, and it is also open to the air at the bottom through the loose-fitting screw-cap f, so that any slight leakage ot' gas into this space becomes rapidly diffused and carried oft' by the air circulation thus allowed therethrough, thereby preventing any such accu mulation as would tend to permanently scent the drop-tube and cause it to give out an uupleasant odor when drawn down; but this feature I do not here claim, broadly, as the same is shown in a previous pat-ent issued to me November 7, 1876. i

Now, t' indicates an annular coupling, which screws onto the inner coupling, a, and extends below it, and k k indicate two semi-annular tubes of large diameter, which junction closely together diametrically, as shown best iu Fig. 2, and by dotted lines in Fig. 1, and encircle and inclose all the inner tubes ot' the chandelier, being screwed at the upper end into the annular coupling i, and at the lower end into the hollow hub Z, from which the branching arms m extend, as fully shown in Figs. 1 and 2. The upper end of the semi-annular tubes 7c k screw sufficiently far into the outer coupling z', so that their inner edges abut against the lower edge ot' the inner coupling, a, as shown in Fig. 1. After the semi-annular tubes are screwed into the position shown they are soldered in place by the blow-pipe, or by what is known as sweat-ing,77 so that the solder will follow or iiow over all the line capillary spaces or surface between the joints, thus making the connection lirm and gas-tight without closing the narrow semicircular mouths of the annular tubes. It may now be seen on reference to Fig. l that the lower end of the semiannular tubes 7c lc opens into the hollow hub l, from which thebranching arms m extend, while the upper end thereof opens into an annular space between the couplings a and i, into which oblique holes n a are bored from the central gas-passage of the coupling, through which holes the gas is admitted to the semi-annular tubes, and thence through the hollow hub Zto the arms m, which support the stationary lights, inthe usual manner.

It will thus be seen that by my invention the semi-annular tubes k 7c, in which the chief novelty lies, form the gas-passage to supply the Xcd arms ofthe chandelier, and that this passage is complete in itself, and distinct from the central passage, I), which supplies the droptube; hence, as the outer tubes or ducts of the chandelier which supply the arms and inclose the inner tubes are by my invention made in sections or halves, it will be observed .that the parts may be thus put together in a more quick and simple manner than is the case with continuoustubes. Furthermore,itwillbeseen that the tube e, which incloses the drop-tube, is by this construction kept from contact with the gas, both on its interior and exterior sides, except for a small portion where it passes through the hub l, and that the drop-tube thus moves iu a free air-space within said inclosin gtube, as before described, so that the scenting of the exterior ofthe drop-tube is thus eectually obviated,wl1ich forms a most desirable advantage ot' this construction, as will be appreciated.

It should be mentioned that the hub l is, of course, soldered to the tube c where the latter projects therefrom, so as to render the connection firm and gas-tight, and that, furthermore, the solder fastening the lower end of the semiannular tube is designed to run into and close the lower end of the slight space between the tube e and the semi-annular tubes 7c k, as at r, so as to prevent the gas rising between said tubes, and thus form a dead-air space between the same, as will be understood.

It will be obvious that instead of making the divided tubes k k in two divisions, three or more may be used; but it is apparent that two semi-annular tubes or diametrical divisions are preferable.

What 'l claim isn 1. A drop-light chandelier having its stem constructed with semi or partially annular tubes 7c 7c, inclosing` the inner tubes,and forming a distinct gas-duct to'supply the iixed branches of the chandelier, substantially as herein set forth.

2. A drop-light chandelier having its stem composed of the central gas-tube, b, drop-tube c, sliding thereon, and third tube, e, inclosing the same and open to the air at top and bottom, with the semi-annular tubes 7c 7c, inclosing the latter and forming the gas-duct to supply the tixed arms of the chandelier, substantially as shown and described.
